Lightweight modified asphalt waterproof coiled material
The invention belongs to the technical field of asphalt waterproof coiled materials, and particularly relates to a light modified asphalt waterproof coiled material, which has the advantages that fly ash is gray fine powder, is a byproduct generated in the coal combustion process, and can improve the durability and crack resistance, the weight of superfine fly ash is lower than that of common fly ash, and the weight of the coiled material can be reduced; the asphalt is hard asphalt, the formula of the hard asphalt is as follows: asphalt with the needle penetration of 1mm, dehydrogenated asphalt and asphalt with the needle penetration of 10mm are mixed according to the ratio of 1: (0.2-0.5): (4.5-5.5), the asphalt is lighter than water, the density of the asphalt is less than 1, and the asphalt is one of main components of the waterproof coiled material and provides a main protection function of a waterproof layer; polymers or other additives are added into the modified asphalt to improve the flexibility, weather resistance and aging resistance of the modified asphalt, and the asphalt with the density smaller than 1 is lighter than water, so that the weight of the coiled material can be greatly reduced.
本发明属于沥青防水卷材技术领域，尤其涉及一种轻质改性沥青防水卷材，本发明优点：粉煤灰是一种灰色细粉末，是煤燃烧过程中产生的副产品，可以提高耐久性和抗裂性能，超细粉煤灰的重量比一般粉煤灰更低，可以降低卷材的重量；沥青为硬沥青，硬沥青配方为：针入度1mm沥青、脱氢沥青和针入度10mm，沥青按1:0.2‑0.5:4.5‑5.5的比例混合，沥青选用比水轻的沥青，沥青密度小于1，沥青是防水卷材的主要组成部分之一，它提供了防水层的主要防护功能，改性的沥青在其中添加了聚合物或其他添加剂，以提高其柔韧性、耐候性和抗老化性能，而密度小于1的沥青比水要轻，这样也可以大幅度的降低卷材的重量。
